[Mailman-Users] attachment handling

Hi list

i'm having trouble with attachments, because my users want to send mails with them and i don't want them to, so i've restricted the message size to 40kb.

i wan to know if there is a way to "detach" the attachment, place the file on a public web server and provide a link into the message to download the file from the webserver.

can i do that with mailman, mailman/postfix or mailman/exim?

i am using a separate domain for the lists, and a a separate MTA so i can modify almost everything.

thanks
